Abstract

Background

The aim of this study was to predict intraoperative graft diameter with our new method by evaluating the cross-sectional areas (CSAs) of the hamstrings in axial sections of MRI.

Methods

This study included 78 patients who underwent single-bundle ACLR between 2022 and 2023. MRIs of the patients were evaulated preoperatively and four CSAs of the hamstring tendons were measured in two different regions by two participants. CSA measurements were calculated manually and the total area was measured by adding up these cross-sectional areas separately. This value was considered as the area of a single circle and the radius was calculated using the area formula of the circle (A = πr²)

Results

For participant I, perfect agreement was found in semitendinosus measurement (κ = 0.849), moderate agreement was detected at the medial condyle level (κ = 0.520). For participant II, perfect agreement was found in the medial condyle region (κ = 0.849), substantial agreement was obtained at the joint level (0.631). In the gracilis tendon evaluation of both participants, substantial and moderate agreement was found at the joint level and at the medial condyle level, respectively. CSA of hamstring tendons measured at the joint level by both participants were found to be positively correlated with the intraoperative graft diameter (r = 0.51) (P < 0.05)

Conclusions

Preoperative MRI assesment could be a effective tool for determing preliminary information about the hamstring graft diameters. Moreover, it is observed that quadruple hamstring graft sizes were more correlated with MRI measurements at the joint level than medial condyle level by using circle area formula.

磁共振成像在前交叉韧带重建中预估腘绳肌腱自体移植物直径的新方法。

背景：本研究的目的是用我们的新方法通过MRI轴向切片评估腘绳肌的横截面积（csa）来预测术中移植物直径。方法：本研究包括78例在2022年至2023年间接受单束ACLR的患者。术前评估患者的mri，并由两名参与者在两个不同区域测量腘绳肌腱的四个csa。CSA测量是人工计算的，总面积是通过将这些横截面积分别相加来测量的。结果：参与者1的半腱肌测量结果完全吻合（κ = 0.849），内侧髁水平测量结果吻合（κ = 0.520）。对于参与者II，内侧髁区域完全一致（κ = 0.849），关节水平基本一致（0.631）。在两名参与者的股薄肌腱评估中，分别在关节水平和内侧髁水平发现了大量和中度的一致。两组患者在关节水平测得的腘绳肌腱CSA与术中移植物直径呈正相关（r = 0.51）
